The attached patch makes the cbd program (the stand-alone version of 
the fileserver's callback.c) work again.

(Now I expect 99% "what's that?" and 0% "what a relief!" reactions. As 
a reminder that's one of the things you might go hunting for after a 
'kill -XCPU' to the fileserver - this program is probably used 
infrequently but the older you get... )
